摘　　要：在以食用菌下脚料金针菇渣为主配制的4种基质基础上,比较了用味精废母液制备的营养液与完全营养及清水浇施番茄的营养效应.结果表明除基质1因菇渣的二次发酵对番茄生长有一定影响外,番茄在添加适量加土壤的基质2、3、4上都表现出良好的长势;味精废母液不仅能满足番茄所需的营养要求,而且其营养效果优于纯无机的完全营养液.指出用味精废母液作基质栽培的营养液其关键技术是调节稀释液的电导率至栽种植物所能接受的水平.同时发现,以食用菌下脚料配制无土栽培基质时须防止其二次发酵产生的影响.The effects of waste mother liquor of monosodium glutamate and complete nutrition solution as nutrient supplement on tomato plants were compared. The tomato plants were grown on 4 different culture matrixes all prepared mainly from waste culture medium for edible fungi. Results of our experiment showed that on matrixes ②, ③ and ④, where soil was an indispensable component, the growth and development of tomato plants were basically normal, whereas growth of plants on matrix ①, in which the soil component was lacking, was relatively poor due to occurrence of secondary fermentation.
